A33 · Reference edition 2026.11
Contact pads — Comparison and alternatives
Pad shape, material and replaceability affect the interface description. Record where the part touches rather than relying on a catalogue image.
Scope and purpose
Compare alternatives using the same question and context. A difference in wording, layout or scale is not automatically a difference in performance. Keep the original observations available and explain which differences are meaningful for this comparison.
Working notes
This reference collection concerns light, offline dimensional-inspection layouts. It brings locating concepts, component descriptions and revision records together without substituting for an engineered fixture design. The drawings are original explanatory diagrams. Reference IDs identify documents, not commercially tested products. Read the scope and limitations alongside each example, and keep the actual part drawing and inspection requirements available when reviewing a proposed layout.
Practical example
Distinguish a flat, curved, annular or replaceable contact in the component record.

| Limits and interpretation | Material compatibility requires knowledge of the actual part surface and conditions. |
Review checklist
State the comparison question; align context and labels; list common features separately from differences; leave unsupported conclusions open.
